I had originally posted this question on another forum. After seeing the web address to this place in a magazine, I thought it better to post here. The original post has been slightly edited to respect the rules of the forum regarding web links and price discussion.

I have been looking at HDTVs. I think it best that I go with a 32'' set. Some brands I was looking at were Toshiba, Samsung, Dell, and Sharp Aquos, or possibly a 37'' set. The 37'' Dell and 37'' LG televisions look good to me. I will include some model numbers at the end so that anyone interested can get an idea of what I am lookng at.

Now, will I need a tuner built in to play the 360 in true HD? It is my understanding that no tuner is needed to watch HD cable or sattelite because the boxes they give you from your cable company, Dish Network or DirecTV will process the digital signal on their own. The tuner is only needed to pick up stations from local broadcasts which are in HD or to take advantage of the picture in picture feature of the TV. So to get the most out of the 360 in HD is a tuner needed?

Next, the native resolutions of a lot of the TVs I looked at was 1366x768. How do I know if that is 720p or 1080i? It sounds as though it is 720p. I want one in the widescreen 16:9 formatt which most are nowadays, so if you take the 1366 and divide by 16 then multiply that by 9 you get 768.75. Which is what I don't understand, does that mean it's just 720p? Which would be best for games in the first place, but I would like a television that can do true 1080i and not just scale it down to 720p because I doubt the difference for gaming would be so great that I would notice. Maybe only when you're changing weapons in a FPS game or some similar quick action. Also the resolution is somewhat important to me since I would like to take advantage of the PC inputs on most TVs and the 1366x768 resolution is not supported as a native one by most PCs.

The contrast ratio I am unclear on, I am thinking the lower the number the better. For example 800:1 or 600:1 are better than 3000:1 or 1000:1. That is basically an uneducated guess, but is it a correct one?

As far as inputs, I need at least two component inputs, RF is useless to me basically but they will come standard anyway. A/V, composite or RCA inputs, whatever you want choose to call them, it would be helpful to have as many of those as possible. Most sets offer two or three of these inputs, but I think the Dell offers eight. Of course the PC input is a plus. But what exactly is a DVI with HDCP input? I am only familiar with the HDMI input and want a set with an HDMI input.

LG 37'' LCD - model number DU-37LZ30
Samsung 32'' LCD - model number LN-R329D and LN-R328W
Toshiba 37'' LCD - model number 37HL95
Toshiba 32'' LCD - model number 32HL95
Sharp AQUOS 37'' LCD - model numbers LC-37GBU5 and LC-37D6U
Dell 37'' LCD - model number W3706MC

Thanks for reading and any answers, comments or suggestions are appreciated.

i'll try to help...

if you want "TRUE-HD" you need a panel that is 1920x1080. panels less than this that can process 1080 will use a internal scaling engine to re-fit a 1080 source to the native pixel size of the panel.

higher contrast ratios are better.

dont get to hung up on "16:9", if the physical panel is in 16:9 you're good.

HDCP is a data stream ("channel") that carries encryption data along with the video channel. DVI and HDMI each define a type of physical termination. DVI carries only video while HDMI carries video and audio, both carry the exact same video signals....

many cable boxes have DVI or HDMI outputs which you can use to connect to a AV unit or directly to your panel.

as far as panels are concerned, i dont know which one would meet your connectivity requirements...

hope this helps.

Most panels in 32" and 37" are 768 vertical. This is generally considered the "native" 720p resolution. 1080i will be "scaled", regardless of the panel because it's interlaced ("i"). So on a 1080p panel, successive 60Hz 1080 frames will be combined to produce 30Hz 1080 frames. Generally, on a 720p panel, the 1080i frames (which are really 2, 540 line frames) will be up-scaled to fit the 720p. There are no 1080p signals as of yet, so buying one is guessing at a future-proof solution. IMHO, at 32 or 37", a 1080p panel is not a smart move. The actual resolution difference will be next to impossible to see at normal viewing distances (even game console distances), and the internal video scaler will need to work MUCH harder to obtain the same picture quality (scaling, motion blur) as a 720p panel. For quite a while, most programming will still be SD. Imagine how much harder it must be to properly scale a 480i signal to 1080p than to 720p. Many, many more pixels the scaler must "guess" at.

Having a built-in HDTV tuner is a good idea. You don't need it for gaming, as you would hook your console to one of the component or composite inputs. However, OTA HD signals for your local channels are generally far less compressed than the pay-tv signals. This is especially true w/sat signals. Side-by-side the difference is noticable.

Don't put too much stock in contrast ratios. There is no standard of measurement, so one company's 3000:1 could be the same as another's 600:1. But if you're comparing 2 sets from the same company, higher is better. You're better off using your own eyes (if possible) or lurking around these forums for user's opinions.

Nowadays, all name-brand panels have at least one HDMI input (some have 2 - like the Dell, I think), at least 2 component inputs, several S-video/composite imputs (these are sometimes shared) and a VGA input. Usually the only RF input is for the antenna.

Personally, I'm looking to get the Tosh 37HL95 when the price comes down just a little bit more. It's gotten great user reviews, especially for SD viewing (and at 36.09"W, will just fit into my cabinet!).

Just to be totally precise -- a 768 panel is neither 720 native nor 1080 native. It is 768 native and both 720 and 1080 will need to be scaled. "Scaling" refers to matching resolution, which is independent of "i" or "p". Converting i to p is "deinterlacing".

Agreed. Just trying to keep the technical jargon to a minimum. :) Hence all the ""s.

As of this year, getting TV less than of true HD 1920x1080 native resolution is a waste of money and dumb since almost all of HD broadcastings are 1080i. Despite what other people say about normal viewing distance probably couldn't differentiate if it is 720 or 1080 resolution, a true HD 1920x1080 native resolution won't need a scaler when receiving a 1080i signal so is more or less picture perfect.

Watching HD PBS on native 1920x1080 TV is really mind blowing!! All the colors and details, it is truely a 24hr, 7 days week HD channel.

A 32" widescreen TV will definitely look a lot smaller than 32" SDTV, so 37"-42" would be a better choice. The Consumer Electronics Show (CES) is coming up on 6th of January, so you should hold your horse for a while. With >37" LCD TV, you should definitely looking for a true HD 1920x1080 native LCD TV. It simply blow any 1366x768 or 1024x768 away if you are feeding a HD 1080i signal. For a budget of $2,200, I suggest you can look at BenQ DV3750, a 37" 1920x1080 native LCD TV. The review is quite good, and if you don't need cablecard, ATSC tuner, or HDMI (it has DVI), then this is a good bet.

Review: http://asia.cnet.com/reviews/home_a...9094440p,00.htm

The actual PC input resolution is actual 1360x768 despite what the review said. Someone actual did manage to get PC 1080i working over DVI - another big plus.
